JOSEPH J. GILL, OF S'IEUBENVILLE, OHIO.

MACHINE FOR FINISHING OPEN-ENDED GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 249,751, dated November 22, 1881,

Application filed May 10, 1880.

To all whom it may concern:

Be it known that I, JosEPH J. GILL, a resident of Steubenville, in the county of Jefferson and State of Ohio, have invented certain new and useful Improvements in Machines for Finishing Open-Ended Glassware; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to the manufacture o glassware, and its object, more particularly, is to provide a machine in which the delicacy of touch and precision obtained by a hand-tool is united with the rapidity of motion imparted by power, it being specially adapted to thefinishing of open-ended glassware.

The invention consists of the combination, with the hand-tool, of a tool rest or carriage and certain mechanical elements whereby the tool can be advanced and withdrawn from the work with greater precision and accuracy in finishing articles where it is important that the finished end shall be central with or in the axial line of the body of the article.

In the drawings, Figure 1, Sheet 1, is a side View of the hand-tool, adapted to have the shapin g-blades revolved by power and expanded by means of hand spring-power. Fig. 2 is cross-section at X X; Fig. 3, a central longitudinal section at X X, Fig. 4; Fig. 4, an end view of tool-head. Fig. 5, Sheet 2, is an end view of the tool connected with a tool-carriage and means to operate the device. Fig. 6 is a longitudinal section at X X Fig. 5. Fig. 7 is a sectional plan at X Fig. 5. Fig. 8, Sheet 3, represents what is known as a universal swing-frame with my tool attached.

Like letters of reference refer to like parts.

In Sheet 1, A is a driving-shaft, extending the entire length of the tool through a tubular easing or pipe, B. Attached to the end of the pipe B is a circular face-plate, 0, having lugs a. a, to which are pivoted two crank-levers, D D.

E is a revolving disk set in the face-plate C, and held in position by plates 1) 1) b It re- (No model.)

ceives its motion from the shaft A, which is flattened on opposite sides a portion of its length, where it passes through the disk, as shown fully in Figs. 2 and 3.

F is a slotted cross-head, attached by means of standards 0 c to the disk E. I

y y are set-screws to regulate the width of opening for the blades.

G G are removable tool-blades, constructed to engage with and slide on the cross-head F.

H H are crank-levers pivoted to the standard c c, and attached to the shaft A and tool blades G G by means of a slot-and-pin connection.

J J are spring-arms secured to the pipe B at d, and connected with the crank-levers D D by a slot and pin. K K are connecting-bars pivoted at e c to the crank-levers D D, and connected to the shaft A by means of the end extending at right angles through a slot in the sleeve-connection of the pipe B into an annular groove between two collars, g g, on the shaft, the bars being secured from any displacement by a connecting ring or band, h, around the pipe B, to which the bars are fastened.

In Fig. 6, Sheet 2, L is a platform or table, mounted on suitable supports, 1 l.

m m are standards to support the operating mechanism.

M is a cylindrical tube of suitable size to .receive the tool-shaft A and easing B. The

shaft A is extended through the cylinder M into atubularborejournal-hearing,a. Rotary motion is imparted to the shaft by means of a slip-band pulley, n, the shaft being flattened a,

projecting arm, a to which is pivotedahandlever, at, having a bifurcated or forked end, which engages with the shaft A between the collars g g; a, spring to hold lever in place. This hand-lever takes the place of the handsprings and cranklever connections (illustrated in Sheet 1) for operating the shapingblades, the tool in every other respect being similar to that therein shown and described.

In operating the hand-tool power is applied, preferably by means of flexible shafting, to the shaft A, which revolves the tool-blades G G. The tool is then grasped by the hand of the operator over the spring-arms J J, and by compressing the spring-arms the tool-blades G G are made to open outward from each other on the slotted cross-head F until they strike the set-screws 3 y, which regulate the size of opening to be madein the ware by means of the bell-crank levers D and H, which move the tool-connecting frame-work to and fro on the shaft A. The blow-pipe, to which the chimney or other article is attached, is placed on suitable rests in such a position that the workman can insert the tool in the perforated end and enlarge the opening and shape it as desired.

The mode of operation when the tool is mounted 011 a stationary tool-carriage is as follows: The article to be opened is placedin the axial line of the center of the tool-head, on suitable rests in front of the machine. Power having been imparted to the driving-shaft, the operator grasps the handle a and draws the tool-head and shaftin g forward into the article to be opened, at the same time expanding the tool-blades, by means of pressure on the lever a, to the proper distance, as regulated by the set-screws in the end of the slotted cross-head.

The shaping-blades G G are removable, in order that others can be substituted when desired. The working face or edge of these blades can be of any shape or configuration required to form the article. For instance, the outer portions may be straight and parallel with each other in their outward movement, while the inner portion or shank may be inclined outward from the straight portion, servingto form a cone-shaped or flaring-mouth opening in the ware when the blades are revolved. With a tool having blades of this character the operator can open up the end and form the straight portion of alamp-chimney or other like article with the straight portion of the blades, then reverse the article and open the end and flare the mouth with the inclined shanks of the blades, thus avoiding the necessity of substituting another set of blades to flare the article.

The swing-frame represented in Fig. 8 is composed of rods B and E and intermediate connections. The rod B is swiveled in a forked arm, I, pivoted to a shaft, N, turning in bearings fixed to the ceiling, to which motion is applied by means of suitable connections. The rod B extends downward from the shaft N, and is provided at its lower extremity with another forked arm, L, to which it is also swivcled. The arm L isprovided with sleeves C at its ends, as shown, which form bearings for the shaft of a pulley, C, turning between the bifurcated ends of the arm.

To the sleeves C of the arm L is rigidly secured the forked arm D, to which the rod E is swiveled, in the same manner as the rod B, to the arm L. A pulley, A, turns upon the shaftN, between the forked arms OH, and communicates motion from the shaft to a small pulley, M, rigidly secured to the pulley C, and working on the same shaft by means of band or rope connections. communicated by the large pulley, O, which receives motion from the small pulley, to another pulley, K, which turns upon a shaft fixed between the bifurcated ends of the rod E, and in which bifurcated arms the said shaft has its bearings. This shaft (marked K) is prolonged uponjone side for attachment of the tool H, heretofore described.

In order to hold the rod E in an approximately horizontal position, I provide a weight, V, as shown, provided with rope or band running in pulleys attached to the ceiling, and from thence to about thecenter of the rod E. It will be apparent that this device facilitates the use of the tool and admits of it being used in any required plane.

I am aware that glass-finishing tools have been provided with a foot-treadle by which a sleeve is given a longitudinal movementwhich also expands the tool-blades; but I am not aware that it has been possible to use a tool operated with the speed of machinery by which all the movements are accomplished by hand, and I therefore disclaim the construction noted.

Having described my invention,what I claim, and desire to secure by Letters Patent, is-

1. In a hand tool for opening and finishing glassware, the combination of a head carrying the tool-blades, a driving-shaft connected to such head and adapted to rotate the same, a tubular sleeve on such driving-shaft connected to the tool-blades, and a spring handlever for giving to the driving-shaft and tubular sleeve a longitudinal movement, whereby the blades are at the same time moved outwardly from each other and from the center of motion, substantially as described.

2. A hand-tool for finishing glassware, connected to flexible shafting so as to have a universal movement.

3. In a hand-tool for finishing glassware, the tool-blades carried by the revolving head, in combination with the spring-arms J and intermediate crank and lever connections, whereby the expansion of the tools is directly produced by the compression of such arms.

4. A spring-handle connected to the sleeve and rotating shaft, as described, to move forward said sleeve and the head carried thereby, and also adapted, by compression of said han- Motion in turnis IIO dle, to move the shaft within the sleeve and open the blades, as set forth.

' 5. In a hand-tool for shaping and finishing glassware, the combination ofthe radially-ex- 5 panding blades G G, slotted cross-head F,

the levers H H, driving-shaft A, sleeve B,

spring-handles J, crank-levers D D, and connections K K.

In testimony that I claim the foregoing as my own I hereunto affix my signature in pres- 10 I SAMUEL K; MoKEE, GEO. K. STORM.
